Unequally-spaced deformation absorption device and construction method thereof

Abstract

The invention provides an unequally-spaced deformation absorption device and a construction method thereof. The device comprises a base layer backfill soil layer, a sleeper beam and a deformation absorption device which are sequentially arranged from bottom to top, a guiding plate and a wiring road surface located at the two sides of the deformation absorption device respectively and a road surface structural layer. The deformation absorption device comprises a continuous bending corrugated sheet steel set with the corrugated cross section. The corrugated sheet steel set comprises a flat steelplate which is horizontally arranged and extends to the surface of the guiding plate and the wiring road surface, and a transverse corrugated steel plate located at the middle of the upper portion, apair of U-shaped vertical corrugated steel plates connected with the lower end of the flat steel plate are symmetrically arranged below the two ends of the transverse corrugated steel plate, elasticfilling layers are arranged between the transverse corrugated steel plate and the vertical corrugated steel plates at the two sides, a sliding layer is arranged between the upper end of the sleeper beam and the lower end of each vertical corrugated steel plate, a sliding layer is arranged between the guiding plate and the outer side of one vertical corrugated steel plate, and a sliding layer is arranged between the outer side of the other vertical corrugated steel plate and the wiring road surface. The device is simple in structure and reasonable in design, the phenomena that differential settlement happens on the bridge road surface in successive and rod surface top expansion is caused are effectively lowered, the bridge quality is improved, and the practicability is achieved.

Description

technical field [0001] The invention relates to a variable-absorbing device with unequal spacing and a construction method thereof. Background technique [0002] In traditional bridges with seams, the expansion joints of the bridge are the weak points in the design of the bridge structure, and have become one of the difficult problems in the construction and maintenance of the bridge. When the device is damaged, it is often accompanied by cracking and damage of the concrete connected to it. Over time, uneven settlement and swelling of the road surface have occurred in this part of the road, which greatly reduces the service quality of the bridge and affects the bridge structure. safety and durability. [0003] Traditionally, the problem of easy damage to bridge expansion joints has been solved mainly by improving expansion devices or canceling expansion joints. Improving the expansion device can only reduce the replacement cycle and damage of expansion joints, but it canno...

Problems solved by technology

Improving the expansion device can only reduce the replacement cycle and damage of expansion joints, but it cannot fundamentally solve the maintenance and replacement problems of expansion joints. Reducing or even canceling expansion joints can fundamentally solve the problems caused by bridge expansion joints. replacement problem
